flrlginal aplflication filed. December 4, 1918, Serial No. 265,245. Divided and this application filed January 21, 1926, Serial No. 82,710. Renewed hiareh 5, 1927.

"this invention relates to machines for use in the manufacture i boots'and shoes, and is herein illustrated as embodied in a multistation machine tor performing operations on the heels of boots and shoes of the type oscd. in my co-pending application i Ho. 265,245, filed Deeemher t, 1918, of which this application is a division.

Machines of the type referred to are each provided with a movable carrier having thereon a plurality of shoe supports and air ranger. to trr; L ter shoe? from a loading station to one or more treating stations, and thence to a discharge station. it is an obiect oi the present. invention to provide improved wm'li-supporting and transferring mechanism adapted for use in machines 01' the type referred to, although in various aspects the invention isnot limited to emhodinientin such machines.

in this end. in accordance with a "feature ot the invention, means are provided for starting and controlling the movement of a carrier illustrated as otthe type referred to,

which me is are arranged to be controlled by shoe jacking means so that improper operation o the carrier is prevented and the operator relieved trom the danger of a pr mature startingot the carrier before the inching operation has been completed. Improperoperation of the jacking means is *ited also, in accordance with another ature ot the invention, by lockingineans arrange. to prevent actuation ot the jacking: means until a shoe supportreaches jack in; position. v

In accordance with other features of the invention, novel shoesupporting and clamping; mechanism provided comprising, in

illustrated embodimentot' the invention, a stop member and an associated sliding arranged toclan'ip a shoe therebetwee As illustrated, an operator-com trolled lever is provid'ed'for applying powerful pressure to the plunger, and the shoe new be auton'i icall v held in clamped position under desired degree of pressure, while it is trdnsterred by thecarrier from the point ot pressure application to a point ot release, by means of a one-way clutch de- Vice co-operating with the plunger to hold it in its clamping position. Vi here a plu rality of shoe supports of this sort are mounted upon a carrier, a single operatorcontrolled treadle may be provided at the loading station arranged to co-operate with any one of. the plungers 01 the clamping devices.

In accordance with other ij'eatures ofthe invention, novel mechanism is providedarranged automatically to unjack the shoe after the work has been carried past the various treating stations and the work of the machine completed. In the illustrated embodiment of the invention, where the transfer mechanism takes the form of an endless carrier, the automatic unjacking means operates as the shoe approaches the jacking station, and the removal of the un-' jacked shoe is facilitated by providing novel means tor tilting a hinged portion of the sliding plunger which supports the work forwardly toward the'operator after it has been unclamped. In the reverse operation of jacking a shoe, novel means are provided for holding the hinged portion in operative position.

Still another feature of the invention consists in the provision in a multi-station machine provided with a movable carrier of novel mechanism arranged so that the operator may unjack a shoe at will at any posi tion of the carrier.

These and other features of the invention will best be understood from a consideration of the following specification taken in connection with the accompanying drawings in which:

The illustrated machine con'iprises an endcar-rier upon which are supported a plu rality of work-clamping shoe supports and a pl u ral ity of tools arranged adjru-cnt to but outside of the carrier in I positimr so that they may be utilized to treat the individiuil nieces on. work which are presented to them by theearrier. These tools. which may take a variety of forms, are arranged. in the pres ent machine, to trim the outer surface of a. heel from one breast cornertothe other, to finish the rand of the shoe and toscour the outer surface of the heel after treatn-rent by the trimming tool, but it will be understood that a variety of other comliiinations ottools may well be substituted for use with the particular form of work support and carrier mechanism herein claimed. The tools, re-

, for treatment.

gardless of their particular character, are preferably rotated or operated continuously and means are provided for periodically moving'the carrier to present the heels of shoes supported upon the carrier successively to the various tools and then auto-maticaIl-y' to suspend movementof the carrier and. to actuate the shoes while in ope:-'-. .tive relation with the tools so that various parts of the heel surface are presented to the tools Whe'n the respective shoes have been treated by the tools, the carrier 1s autt-unatically moi-ed to advance them to the next Station and to return the linishe l' shoe to a discharge-station where it is auton'iatical-ly unjackeel and presented for removal and replacement b another piece of work.

The illustrated machine is built upon a base 16 and isprm 'ided with a plurality of tool-supporting standards 18. A drive shaft is provided. which; is not shown. and power supplied from this drive shaft may conveniently be controlled by means of a lever 20 which, if the transfer of power is by means of belts such as that indicated at 22 in Fig. 4, will take the form of a belt-shifting arrangement. The various tools are mounted upon rotating spindles 24 which are supported in bearings carried by slides 26 that move back and forth across the tops of the standards 18. Each of the tools is surrounded by a casing 28 and suction pipes 80 connected to these casings for the removal of dust or waste material.

The motion of the drive shaft is imparted to the mechanism for controlliing the table the shaft. Secured to the shaft 35, Fig. 3,

is a collar ll against which the hub portion of the loose: member 40' of the clutch bears. llflxiending'from the loose member 40 of the clutch are the arms 42' carrying suitable friction material 453,, and a spring 44 on the shaft 35- is interposed between a collar 46' secured to. the shaft and the hubv of the clutch member 39, the construction being such that the two clutch members will, un-

der the stress of the spring 44, be normally held in operative relation and will, pee force, rotate together, but should any unusual obstructzion occur to retard the member 40 of the clutchthe two clutch members may yield or slip.

Loosely mounted on the shaft 35, Fig. 3, a sleeve 45 on which is splined a clutch member 4:6 having a circular recess 47 en-' gagcd by pins or rolls 48 on the bifurcated end portions of an arm 49 pivoted zit- 501 The clutch member 46 is normally under the influence of. a spring 5-1 tending tomove said. clutch member 46 into clutching engagement with the clutch i-neinber 40, said clutch members havir-rg cmruplemental projecting and recessed portions for positive engagement. as indicated in Fig. 2.

The clutch controlling arm -19 has a recessed extension. 52 which is engaged by a pinfi53 mounted on the lever 54: pivoted at 55, the construction being such that should the lever 54 be. turned clockwise, to the position shown inFig. 3, the clutch member 46 will be moved to the left, as shown. and be (hscngaged from the clutch member 40g. but

and when the clutchmembers are operatively engaged the sleeve l5 will be turned. Trains oi mechanism are connected to the sleeve and control the inovei'i'ients of the several parts of the machine including the work supports and controlling cams as will more fully appear.

Pivot-ally mounted a: 56, Figs. 3 and at, is a jacking treadle 57, the toot engaging end of which normally held elevated by a spring 58, Figs. 1 and 3. Connected to the jacking treadle 57' at 59, Fig. 3, an arm 60 the upper end portion of which carri atch (ll adapted at times, as will pr sently appear, to engage. a lug or projection (32 mounted on the clutch shitting lever [2 spring normally tends to engage the catch til with the lug G2, the construction bemg such that with the parts in position indicated in Fig. 3 should the jacking treadle 57 be depres-ed the catch ($1 will he l fted to carrv its shoulder ahove the lug (2 whereupon the spring 63 will en age tl with the shoulder and, upon release of th jacking treadle 57, the arm '60 will he pulled downwardly thereby to turn the lever Fri: contraclockwise and permit engagement ot the clutch members ll) and 4-6 to start the machine.

Mounted in a suitable step bearing (ll: on the machine base 1, Fig. 4, is the table spindle 0r "shaft 65 to the upper end portion of which is secured the table or carrier, the characteristics of which will he more fully described. I

The spindle or shaft 65 has loosely mo unted thereon the worm wheel 67, Figs. 2, 3 and 4, which is confined between Suitable collars 68 and 69 secured to the spindle or shaft 65. The hub 70 of the worm wheel 67 is elongated as indicated in Figs. and i and has U secured thereto a. series of cams 71, 72,- 73 and 74 for controlling the operative or inoperative condition of parts as will more The worm wheel 67 is operatively engaged witha worm 75, 2 and 8, secured to a transverse shaft 76 rotatably mounted in suitable bearings formed in the risers 77 and 78 projecting i'ipwar-dly from the machine base, substantially as indicated in Fig. 4:. The shaft 7 6 is driven from the clutch memher 46 through an appropriate train of conhereinbefore described, it is desirable that such lever be maintained in position with the clutch members engaged to maintain the series of cams 71, 72 and 73 in operative control of the table, the jacks or work sup ports thereon, and tools, as will more fully appear, until the tools have completed their respective operations upon the heels of the shoes presented thereto and a finished shoe has reached the jacking station, and that then the parts be controlled so to prevent further operation until the finished shoe is removed and another jacked at the jacking station. To this end the huh T0, 3, carries the cam 'H which may he appropriately formed on the face oi the cam 73 and the cam Tl has a depressed portion 8]. The lever carries a projection or rider 82 over which the cam 74 travels, the construction lJGll" uch th t whl l l on tic ever at is turned contraclockwise in the manner hereinbetore described, and the cam 74 is turned throughthc means stated, the projection or rider 82 will travel along the face of the cam and hold the lever 5st in position with the n'iachine in operation. Projecting from the face of the cam 7% is a pin 83, Fig. 3,

which, as the cam 74; rotates, is adapted to the catch 61 on the arm 60 and disengagethe catch from the lug (S2, to that ai ter the projection or rider 82 has engaged the h h part of the cam T l, the lever 54 is 't'reed item control oi the jacking lever 57 and will remain with the clutch members it) and as in engaged. relation until, in the rotation of the cam 74, the depressed portion 81 thereof comes opposite the projection or rider 82, whereupon, the lever 5i, under the impulse of a. spring 84, Fig. 3, will be turned clockwise, to disengage the clutch members 40 and 4:6 and stop operative movement of the machine. 7

In addition to the means described for controlling the engagement and disengagement of the. clutch members a0 and 4.6, other means are provided. operable to stop the machine at the will of the attendant, as will now be described.

Pivotally mounted at 85, Fig. 4-, is an emergency lever 86 (Fig. 1) which extends to thefront of the machine near the jacking station in convenient reach of the attendant. The en'iergency lever 86 has a locking pin and a hand control grip whereby the emergency lever may be moved about its pivot 85 and held in desired position by suitable locking recesses formed in a portion of the'niachine fra he. The emergency lever 86 has projecting arm 90, Fig. 4. which ter minatcs in a. pin 91 engaged with the bifurcated end 92 of a lever 93 pivoted at 94. on

a bracket or lug secured to or formed as part 7 arm 95, Figs. 3 and i, the lower end portion of. which is connected to a toggle for controlling the clutch member 416. In the present exemplification of the invention the tggle comprises the link 96 pivoted to a bracket at 97 fixed to the machine i'rame and connected at its other end at 98 to the other toggle member 99', Figs 3 and 1, the lower end 95 of the lever 03 having a slotted connection with the joint of the toggle at 98 as illustrated in Fig. 3. The toggle member 99 is connected at 100, Fig. 3, to the end 01' a lever 101 mounted for pivotal movement at 50 and carries an adjustable pin 102 adapted, when the lever 101 is moveddownwardly by straightening the toggle, to engage the end of a. finger 103 projecting from the clutch shifting arm 49, the construction being such that should the emergency lever '80,. Figs. 3 and: 4, be turned to the right, Fig. 4t, the lever 93 will be rocked to cause the lower end 95 thereof to straighten the toggle and disengage the clutch. member 10 from the clutch 4-0, thereby stoppingrotativemovement of the hub 7 O and the earns carried thereby and consequently suspending the operative movements of the table and jacks mounted there on. Shifting movement of the emergency lever 86 has additional functions with respect to the movement oi the tools from operative position when the emergency lever is actuated with jacked shoes in position for treatment. by the tools and this characteristic of the invention will later appear.

The shaft 736. Figs. 2 and 4 has secured thereto a'pinion 1.04 which is operatively engaged with apinion 1.05. Fi i and loose 1y inountedon the shaft 106 appropriately journaled in bearings 1:07 sustained by the uaiirights or risers 77,7 8. Fig. 41. The pinion 1:05 meshes with a. gear or pinion 1108, Figs. 4, 5 andti', loosely mounted on the shaft. zuun'opriately supported in bearings 110 sus' tained by the risers 77, 78 as indicated in Fig. 4%. The pinions or gears 105. 108 are adapted to be operatively connected to their respective shafts under ct'introl of the cams 72 73 heretoilore described as rotatable with the worm 67.

In the illustrated machine the hub portionsof the gears or pinions 105. 108 are adapted 'to he chitched to their respective shafts under the control otllorton clutches but. of course. otheriorms on" clutches might be employed. Pivotallv mounted at 111', FigsA and 5, is a lever 112 having an upwardly spring impelled member 113 :nlapted to engage-the shoulder 114 connected with the usual: roll carrier or rage of a Horton clutch. Similarly there is i i'voted at 115, Fig. 5, a

lever 116 having a similarly supported spring member 117 adapted to engage with a: shoulder 118 connected to the cage of the usual Horton clutch. the constructionbeing suclrthat should either of the members 113* or 117 engage with its respective shoulderof the associated Horton clutch, such clutch will be rendered inefieetive vand the gear or pinion with which it is'associated will be operativel y disconnected from its sheik. The pins 113 and 117 carried by the mem: bers 113 and 117* may hold their respective shafts from rotation when in stopped posi tion by entering suitable holes in the usual cam part of the clutches.

The lower end portion of the level-112 connected by an adjustable rod. 119 with a lever 120, Fig. f, pivoted at 121, Fig. 2, and having an arm 122 carrying a roller 123 adapted to bear upon the peripheral portion oi the eamfli. Similarly the lrower end of the arm 116, Fig. 5, is connected by an adjustable rod12l. with :rn'arm 125pivoted at 126 (Fi and having an arm 12?, the end of whici carries a roller bearing against the peripheral portion of the cam 72. Between the arms 120 and 125. Fig. 5, its-interposed a syn-lug 128. for normally pressing the free ends of the arms 120 and 125 away from each other and. perforce. the other ends of the arms carrying the rolls against their respective cams. the construction being such that under the dictates of the earns 72 and T3 the Horton clutches heretofore described will be appropriately operated to connect their respective geaas or pinions 198 or 105 to the shafts 1-09 and 10.6 respectively. The pinions 105 and: 108 are continuously driven by gear 104. when the table and jack operating clutch is closed. and the shaft 106 f or the shaft 109 will be operated whenever its associated clutch is operatively connected to it.

The shaft 106 has secured 'thereto a worm 12!) which is engaged with a worm wheel 130. Fig. at. secured to timetable spindle or shaft. 6n, the construction being such that when the gear'er pinion: is secured to its shaft as hereinhet ore described. the table will be appropriately rotated. a

The shaft 109 has secured thereto a Worm 1'31, Fig. 4, which is engaged! with a worm wheel; 132 secured to sleeve 1%, loosely n'iounted upon the table spindle: or shaft 65 and supported vertically thereon by meansof a collar 1341. The-upper end ofthetahlespim dle or shaft (E rand the sleeve 1233 find suitable bearing 135 in the upper portion of thecross.

comyn'ises four arms 138 (Figs; 4,7 and: 9-) each of whachcarries a shoe support or jack.

Thespace between the arms 138 may be uppropriateliy covered. as by suitable plates (not. shown); thereby toprevent chi-psand they will be suitabl 'uided.

The jack controlling cam 137, F 1 and 7, which, as l'iereinbefore described as scoured to the sleeve 183, is provided with. two can. surfaces or grooves, one for controlling the inward and outward movement of the jacks relative to the table and the other of which is devised for controlling the rotative movement of the jacks and shoes thereon during the operation of the tool or tools upon the heel, the two cams acting conjointly during the heel treating operation by one or. the tools to traverse the heels past the tool at appropriately varying speeds so that the tool shall treatequal extents of surface of the heel during each successive unit of time.

To eti'ect the inward and outward movement of the-jacks the cam 187 is provided with an upper cam groove 14 1, Figs? and 9, which engaged by a roll or pin 145 extending from the arm 1 12 on the slide block.

lrlounted for rotative movement in the slideblock 1 10 is the jacx support 116, Fig. 7. to which is secured or splined a pinion 147. throughthe medium of which the jack to be hereinafter described is appropriately rotated. lrlounted in the arm 1420f the slide block is a pin or support 148, Fig. 7,-

provided with a collar 149 between which and the arm 1 12 is a toothed segment 150, the teeth of which engage the teeth of the pinion 147. When the jacket shoe is operatively positioned relative to a tool, the present invention contemplates movement of the jack to lnove the presented shoe past the tool at angular speeds varying in inverse ratio to the distance of the part being treated from the centre about which the shoe is moved to cause the tool to act in each successive unit of time on a like extent of contour surface for treatment. But when the treated shoe reaches acking position it is desirable that the jack shall be freed from its rotating means in orde' that the attendant may properly accommodate the shoe to the jack.

'io these ends the pin 148 extends below the collar 149 at 151, Fig. 7, and is provided with a sleeve 152, a spring 153 being interposed. between the sleeve 152 and a stop or nut 154. the construction being such that the spring 153 normally tends to lift the sleeve 152 on the extension 151 of the pin 148. The sleeve 152 at its upper portion is provided with a locking pin 1.55, Fig. 8, which is adapted to engage a recess 156, Fig. 10, formed in the toothed segment 150 and. perforce, Lek the toothed segment to the sleeve 1 2, when the two are broughtinto registeri ,1. relation.

The sleeve 152 is connected by a link 157, 7, with an arm 158 pivotally mounted at 159, Fig. 1, to a lug extended from the table arms 188. Each of the arms 158, of which there is one for each jack, has a roll 161), Figs. 7 and 9, adapted to engage appropriate cam tracks or grooves 161 formed in the under surface of the cam 137, the construction being such that when the cam and table are relatively moved and the sleeve 152 is locked to the segment 150, a condition which exists when the jack is in operative relation with the tool, the jack is suitably rotated as hereinbefore described at angular speeds'varying in inverse ratio to the distance of the part being treated from the centre about which the shoe is moved to cause the tool to act in each successive unit of time on an equal extent of the shoe.

When the jack carrying a shoe, the heel of which has been treated by the tool, reaches jacking position at the front of the machine as indicated at A, Fig. 1,'it is desirable that the jack be released from its rotating means and be moved to a convenient position for the ren'ioval of the treated shoe and reception of a shoe to be treated. To this end a spring 162, 7 and 9. is connected to the toothed segment 150 so that when free to respond to the spring, the toothed segment may be rotated to turn the jack into an ap- 'ir-opriate position for the removal of a jacked shoe and the reception of a shoe to be. jacked.

Pivotally mounted at 163 are the arms 164, Figs. 7 and 11, of a bifurcated lever carrying at its end a roll 165. 7, adapted, as the jacked shoe approaches jacking position as indicated at A, Fig. 1, to engage the inclined surface of a cam 166, Figs. 7 and 13, the effect being that as the jack approaches jacking position the roll 165 on the bifurcated lever will be depressed. The arms 164-. of the bifurcated lever. as indicated in Fig. 7, are each provided with a pin or roller 167 which engages a circular recess 168 in the sleeve 152. the construction being such that when the jack is approaching jacking position the end of the bifurcated lever will be depressed and the locking pin155 carried by the sleeve 152 will be withdrawn from the recess 156 in the toothed segment 150, whereupon the spring 162 will turn the jack into an appropriate position for convenient removal and reception of shoes and even though the cam 137 be thereafter rotated during the jacking operation, the jack will not partake of the rotary movement and may be conveniently manipulated by the attendant.

Mounted for vertical movement in the jack block 146 is the jack spindle 169. Fig. 7, the lower end portion of which restsupon'a ball bearing 170 interposed between the spindle 169 and a jacking plunger 171, the whole constituting a series of connections extending downward below the table, the construction bcingsuch that upon upward movement oi the plunger 171 the jack spindle 169 will be raised. in order to hold the jack spindle in its raised or jacked position the present invention contemplates means permitting such upward movement. of the jack spindle and for holding it in jacked position. To this end the jack slide block 140 has connected thereto by bolts 17?. Fig. 12, a depending cap piece 173 in which is mounted the hardened steel block 174 through which passes the jackins plunger 171. The jacking plunger 171 has a flattened face as at 175, Figs. 11 and 12, adapted to be engaged by a locking roller 176, Figs. 7 and 11, which acts as a one-way automatic pressure-retaining clutch as it rides along the inclined surface 177 of the block 174, and under the impulse of a spring seats itself at the contracted portion of the space between the block and the flattened face 17 5 of the plunger to maintain the latter and, perforce, the jack spindle, in the raised or jacked position.

\Vhen a jack with a treated shoe thereon approaches jacking position as indicated at A, Fig. 1, it is not only desirable to have the jack free for attendant control rotatably as ,hereinbetore described, but the shoe should be unjacked. To this end the present invention contemplates the provision 0 means automatically tor unjacking the shoc as the jack approaches jacking position. The steel block 17 1. Fig. 11, heretofore described as contained within the cap piece 173, has lugs 179 projecting therefrom in which is mounted a pin 180, Figs. 7 and 11. Secured to the pin 180 is a rocking lever 181, Fig. 7, having a catch-releasing toe portion 182, adapted to engage beneath the locking roller 176 to lift the same and allow the jacking plunger and jacking spindle to drop down. Mounted on the rocking lever 181 is a roller 183, Fig. 7, which as the ack ap' proaches the jacking station as indicated at A, Fig. 1, with a jacked shoe thereon, is adapted to engage a cam 18st, Fig. 1., secured to the frame of the machine in the path ot' movement of the roll 183 the construction being such that as the jack approaches the jacking station the lever 181 will be actuated to unlock the jacking plunger 171 and permit the jack spindle 169 to drop, being thus guided by the jack support 146 to bring the series of connections by which the jacks are actuated to a normal position.

\Vhen the jacked shoe reaches the jacking station it should not only be unjacked for. convenient removal but should be placer. in convenient position for such removal and the jack parts arranged tor convenient reception of another shoe. Pivotally mounted at 185, Figs. 1. and 7, is the jack block 186 carrying the last pin 187. A spring plungor 188 in the jack block 186 is so arranged that when the jack block is free, it will be swung into the position indicated in Fig. 7, under the impulse of the spring back of said plunger 188. It is desirable, however, that when the jack block is turned into vertical position for jacking the shoe it should be held in such position and then released when the jacking plunger is unlocked to permit drop of the jack. Mounted on the head of the jack spindle/169 at 189, Fig. 7, is a locking catch 190. the end 191 of which .is adapted to engage a shoulder 192 on the jack block 186 when the latter is turned into vertical position and a. spring normally tends to throw the locking catch 199 into locking position. As the jack approaches the discharge and here the jacking position, the jacking spindle 169 drops to unjack the shoe and in order to auton'iatically unlock the jack block 186 at such time to permit the shoe to be swung outwardly for convenient removal, there is mounted upon the jack support 14.6, Figs. 1 and 7. a stop or trip 193 which. as the jack spindle drops during the unjacking operation, hits the end of the latch 190 and unlocks the jack block 186 thereby permitting the spring plunger 188 to throw the block into its inclined outward position, as indicated in f Fig. 7.

lVhere the heels of shoe-s are to be treated about the contour surface thereof, it desirable that the shoe be jacked with the rand crease in a predetermined vertical poeition or that the jacking movement of the shoe be to a. fixed point determined by the thread of the heel. Extending laterally from the jack su port 146 is the arm 191, Figs. 1 and 7, aving a sleeve 195 in which is art justably mounted an arm 196 turned to over hang and serve as a stop :for the shoe hottom, as indicated in Fig. 1, and having pivotally mounted thereon as at 197 (Fig. 7) a toplift plate 198. the shoulder 199 ot which is adapted to engage the breast; o l the heel mounted on the jack when the shoe in jacked position. Automatic adjustment of the last pin 187 to permit proper positioning of the shoe with the breast. of the heel in engagement with the shoulder 199 is permitted by the dovetail sliding connections at right angles to one another between said pin 187 and the jack post 186 shown in Fig. 7. By means of the sleeve 195 and the clamp 200, Figs. 1 and 7, the toplitt plate and, perforce, the position of the tread oi the heel and rand crease may be predetermined for different heights of heels.

Secured to the machine frame, as indi cated in Fig. 7, is a bracket 201 having a sleeve 202, Fig. l, in which is a plunger 2-03 having a head 20% adapted to engage the lower end of the jacking plunger 171 when the jack is in jacking position. The plunger 203 has a suitable recess to engage the head 205 of a jacking lever 2th"), Fig. 7, pivotally mounted at 207 on the n'iachine 'tran'ie and connected by the rod 208, Fig. l, with the jacking treadle 57 hereinbetore described, the construction being such that by depression of the acking treadle 57 a poweriul pressure of substantially any degree within a range may be applied to the jacking plunger 171 ant a shoe mounted upon a jack in jacking position may be suitably jacked.

As hereii'ibefore described the act of jacking a shoe at the jacking station and the re lease of thejacking means or treadle 5'? acts 'to start the machine into ope at-ion, and

when a. shoe has been transferred from the jacl-;ing'station to a tool and has been treated by such tool, the machine automatically comes to a rest by movement of the projection P2 of the lever 54 upwardly into the recess 81 ot the cam 74, Fig. 3. At this time the catch (31 on the arm is disengaged from the lug 62, having been so disengaged by the pin 83 as be'tore described. consequently the clutch'memhers 40 and iti'being now out of engagement. the tablemovement as well as the novement of the jacks relative to the tools as they treat the contour surfaces of the heels, viii be suspended until. after the jack iug operation is again performed and the jacking means or treadle 57 has oeen released. This isdesirable because until a shoe is properly jacked at the jacking station it cannot be properly presented to the tool or tools and it the jack at the jacking station were moved from jacking position by the movement of the table from j table before a shoe is properly jacked, the

jack would be moved avay from the jacking instrumentalities a'ndsubsequent jzi, king oi the shoe would be im 'iossihle. Consequently the initiation of table ant. jack movement to carry the jacked shoes to the tools and tor moving them relative to the tools during the tool operations, are made dependent upon the operation and completion of he jacking means thereby to insure that before these operations are inaugurated a shoe to he treated will have been properly jacked.

It will therefore be apparent that after a shoe has been jacked and the machine has heen started to carry the jacked shoe by 'a'cking position scntcd to the another jack has i and the shoes prehave been treated.

shown), the construction being such that as the table carries the jacked shoe from the jacking station at A, Fig. 1, to the first of the series of tools for treatment, the lug of the jack will engage the yielding stop 225 and the jack will be turned against tlie.ten sion of its spring 162, Fig. 7, to bring the opening 156 in the toothed segment 150, Fig. 10, into register with the pin 155 carried by the sleeve 152 as hereinbefore descriliied, thereby placing the jack automatically under the control of its rotating means.

The emergency lever 86 is also arranged to withdraw the tools from engagement with the work when it becomes necessary arbitrarily to interrupt operation of the machine, and to this end it is connected by a lost motion connection through an arm 234 and a link 5235 (Fig. st) to a vertical shaft 236 mounted in suitable bearings 238 provided in the machine frame. At the upper end of the shaft 236 is an arm 244; (Fig. 4) which is connected to a rod 246 (Fig. 1) arranged to withdraw the tool-supporting slide 26 against the action of a weight 250. Similar connections are provided to each tool slide. At the lower end of this shaft 236 an arm 242 is provided with a roller which travels along the cam 71 (Fig. 2) which is secured'on the hub T0 surrounding the table shaft 65. Thus the tools are also automatically withdrawn from the work at the coniipletion of each cycle. or rotation of the hub 70. y

In the form of the invention herein described, the heels to be treated are secured to the shoe, but the invention in its more comprehensive aspect and with relation to some of the features thereof may advantageously be en'iployed in the treatment of other parts of the shoe when the contour to be followed or treated changes as the tool progresses along the shoe, and likewise heels of shoes may be treated before they are secured to the shoe.

In the use of the machine, the shoes to be treated should be, presented to the tools with the rand creases in approxin'iately predetermined position. If the shoes are without lasts, their positions can be adjusted by varying the height of the jack posts or that part of the jack which goes inside the shoe,

the movable clamping member acting upon the toplitt in this case. In the illustrated embodiment of the invention. the machine is shown for the treatment of shoes having lasts in them, and as lasts vary in height at the heel portion, it is desirable to locate the rand crease, as hereinbefore stated, from a fixed position of the toplift.

After a shoe has thus been jacked by proper manipulation of the combined starting and jacking treadle 57, the release of said treadle will. as will be recalled, connect the intermediate shaft 35 to the carrier and the jack-actuating mechanism and cause the machine to complete a single cycle. During this cycle, the carrier will be rotated through ninety degrees to brin each piece of work to a new station, the too s will automatically be brought into 0 erative relation to the pieces of work, an each of the jacks will be given a combined sliding and rotatory movement by means of which various portions of the surface of the work will be brought into engagement with the par ticular tool with which it is associated.

Since in the illustrated embodiment of the invention the carrier is in the form of an endless carrier, here a rotatable table, the movement of said carrier, to transfer the jacked piece of workto the first operating station, is also effective to'transfer a completed piece of work to the discharge station, which here coincides with the jacking station. As the completed work approaches this position, the jacking plunger will 'be' released under the action of the cam 184 and, as the plunger drops. unclamping the shoe, the last-supporting sectionl86 at'the upper end of said plunger will be tilted forward under the action of spring 188 to facilitate the removal of the completed work and its replacement. by another shoe. Full 0 portunity is given for this removal an replacement becauseof the necessity for depressing and releasing the treadle 57 before the machine will again start upon a cycle of operations.
